Early-type galaxies (ETGs) satisfy a now classic scaling relation Re ∝ σ1.2eI-0.8e, the Fundamental Plane (FP; Djorgovski & Davis 1987; Dressler et al. 1987)...

Borlaff et al. (2014) found that the characteristic photometric parameters of antitruncated discs in S0 galaxies follow tight scaling relations. Now, we have...

Stars with wide brown dwarf companions that host exoplanets are extremely rare, as only four were reported to date. Different theories propose that planets can...

The Hanle effect in strong spectral lines is the physical mechanism that should be increasingly exploited for quantitative explorations of the magnetism of the...

In observations close to the edge of the solar disk, the Ca II infrared triplet has a scattering polarization pattern at the level of 10-3 in its two strongest...

We have developed a spherically symmetric dynamical model of a dwarf spheroidal galaxy using the Schwarzschild method. This type of modelling yields constraints...

Over the past 18 months we have revisited the science requirements for a multi-object spectrograph (MOS) for the European Extremely Large Telescope (E-ELT)...

We present the work developed within the science team of the Very Large Telescope Interferometer Spectro-Imager (VSI) during the Phase A studies. VSI aims at...
